Prime Video announce new true crime documentary from the makers of The Tinder Swindler

"The year is 1978, a young British couple embark on the trip of a lifetime through remote Central America. Chris Farmer and Peta Frampton set out on an exhilarating backpacking adventure, the letters they write and the tapes they sent home were filled with tales of exotic landscapes, cultural encounters, and the thrill of the unknown. But their dream soon turns into a chilling nightmare when they are brutally murdered and the trail for their killer goes cold.

"Four decades later, failed by law enforcement, their family take up the manhunt and begin the descent into an unknown world of online sleuthing and make a shocking discovery.

"This is the story of a gap year gone terribly wrong, and a tale of two families on either side of the Atlantic, united by grief and bound by a common purpose – the pursuit of a killer, even when it seemed untenable, decades after his heinous crimes were committed."
